The evolution of wireless sensor network technology leads to develop advanced systems for real-time monitoring. Wireless sensor network (WSN) is a major technology that drives the development of precision agriculture.By forming wireless sensor network,agricultural practicescan be made good monitoring systems.Various agricultural parameters like soil moisture, temperature, and humidity are monitored by monitoring units.The paper explains about how to utilize thesensors in agricultural practices and explains about routing protocols of wireless sensor network. In this paper, agricultural parameter of temperature will monitor with the use of LEACH protocol.
